According to the Thai Ministry of Interior in 2000, the flag of Chaiya Phum
province is black with the provincial seal in the middle of the flag. It should be noted that on
vexilla-mundi.com, Mello Luchtenberg
shows a flag horizontally divided maroon/orange/maroon (1:2:1) with the
seal in the middle and the name on the province beneath. Olivier Touzeau,
